An environmentalist estimated the number of migrating whooper swans at a lake. He then estimated the number of whooper swans on each of the next six weeks. 0,555 1,562 2,629 3,756 4,943 5,1,190 6, 1,497 a. Choose a quadratic function that models the data as a function of x, the number of weeks. b. Use the model to estimate the number of whooper swans at the lake on week 8.

B.P(x) = 30x2 − 23x + 555; 2,291 whooper swans

Step-by-step explanation:

fill in 8 for x

30(8)2 - 23(8) +555 = 2291

B is your answer

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
